title: Tracking and visualizing chronic headache trends through the use of linked mobile and desktop websites.
abstract: Many people suffering from chronic headaches use headache diaries to help track trends in their episodes. Studies have shown that electronic headache diaries are more effective than paper diaries for both patients and providers. We de-signed and implemented a full-size and mobile Web-based headache tracker and a database management system to store the data from the websites. The fullsize website allows users to retrieve their data by viewing or downloading a table of the raw values they entered, or they can see a graphical visualization linking the severity of their headaches to any of several variables. Through this system's capacity to illustrate trends and track contributing factors for headaches, users, researchers and health service providers may gain better understanding of and control over chronic headaches.
